The Ten Commandments are found in the Old Testament Book of Exodus in the Holy Bible, right after Genesis.  The below Commands (in green) is from the New International Version (NIV) translation.  Blue text is Ray's commentary on what it says.

Exodus 20:3-17

1.   You shall have no other gods before me.

The God of the Bible; the God of Abraham, Isaac and Jacob; the God who created Heaven and Earth and you and I: that God wants to be number 1 in your life.  Anything that you value in your heart ahead of God, in God's eyes, is a "god" (small "g").
2.   You shall not make for yourself an idol in the form of anything in heaven above or on the earth beneath or in the waters below.  You shall not bow down to them or worship them; for I, the LORD your God, am a jealous God, punishing the children for the sin of the fathers to the third and fourth generation of those who hate me,  but showing love to a thousand [ generations] of those who love me and keep my commandments.

   An "idol" can look like, for example,  a statue as well as money or drugs or gambling or pornography or possessions or clothes or cars or even following someone who teaches us any way other than what God has given us in the Bible.  God wants to be number 1 in your heart.
   You also are parted from God when you have not accepted (rejected) in your heart His one and only Son Jesus Christ, who died and rose again from the dead to pay the price in full for your sin. A Christian loves God
and keeps God's commandments.  Jesus says that there is no one who is "good".  "For all have sinned and fall short of the glory of God." Romans 3:23
3.   You shall not misuse the name of the LORD your God, for the LORD will not hold anyone guiltless who misuses his name.

Don't use the name of God or Jesus or the Holy Spirit in any other way than in love.
4.   Remember the Sabbath day by keeping it holy. Six days you shall labor and do all your work, but the seventh day is a Sabbath to the LORD your God. On it you shall not do any work, neither you, nor your son or daughter, nor your manservant or maidservant, nor your animals, nor the alien within your gates.  For in six days the LORD made the heavens and the earth, the sea, and all that is in them, but he rested on the seventh day. Therefore the LORD blessed the Sabbath day and made it holy.

Working on the Sabbath is an issue for God.  He rested on the 7th day; He wants us to do the same. 
5.   Honor your father and your mother, so that you may live long in the land the LORD your God is giving you.

A commandment with a wonderful promise for you.
6.   You shall not murder.

Jesus says that anyone who is angry with his brother will be subject to judgment.  Jesus finds no difference between a person who murders and a person who is angry with someone in their heart.
7.   You shall not commit adultery.

Jesus says that anyone who looks at another person lustfully has already committed adultery with them in their heart. 
8.   You shall not steal.

If it isn't yours then simply don't take it.
9.   You shall not give false testimony against your neighbor.

Gossiping or telling lies or saying false things about others (in court or anywhere) is against God's law.
10. You shall not covet your neighbor's house. You shall not covet your neighbor's wife, or his manservant or maidservant, his ox or donkey, or anything that belongs to your neighbor."

If it doesn't belong to you keep your hands (and heart) away from it.
